📝 Description of the feature

We want to be able to run some automated steps when a new set of documentation is added to DevRelDocs to help us during the PR approval process.
Some examples are:

• if the documentation is in zip format then open the zip and check the validity as per this documentation - https://doc-guidelines.dev.ansysapis.com/docs/migrate-dev-portal/migrate-package/doxygen-package/#preparation-of-the-output
• if the documentation is a OpenAPI example then we want to run a swagger test using this document and check if this is valid or now
• if the documentation is md format we want to run Vale linter against it and make sure it has a introduction/changelog pages.
  This is a good start, but expect more to come.
  A good example of a similar implementation could be found here:
